1891 J. N. Langley & C. S. Sherrington in Jrnl. Physiol. 12 278 It will be convenient to have a short name for the nerve-fibres, stimulation of which causes contraction of the erectores pilorum. We shall call them ‘pilo-motor’ fibres on the analogy of ‘vaso-motor’ fibres.
1899 T. C. Allbutt et al. Syst. Med. VIII. 86 There are the waves of goose-skin passing over the body due to stimulation of the pilo-motor nerves.
1927 Jrnl. Physiol. 64 98 Shallow incisions..through the layers which contain the insertions of the pilomotor muscles into the hair roots.
1998 N. E. Aiken Biol. Origins Art vii. 131 While this study lacks many controls..it does, nevertheless, suggest that the pilomotor reflex is stimulated by music.
B. n.
A pilomotor nerve; an arrector pili muscle.

1892 Jrnl. Physiol. 13 701 This class of fibres consists of the eye-fibres of the sympathetic. Langley has shewn this for cat and rabbit, and they often in monkey extend a segment higher than do the pilo~motors for the scalp.
1932 Amer. Jrnl. Physiol. 102 30 The pilomotors reacted..to single shocks.
1948 A. Brodal Neurol. Anat. xi. 394 The hypothalamus is probably concerned in integrating the activity of the pilomotors with other autonomic functions.
1974 V. B. Mountcastle et al. Med. Physiol. (ed. 13) I. iv. 123/2 The multi-unit muscles include the pilomotors.
